The number of protons and neutrons in carbon-11 and oxygen-15. Introduction: Atoms are the smallest particles capable of independent existence. These consist of electrons, protons, and neutrons. Protons and neutrons are present in the nucleus, while electrons are present around the nucleus in shells. An atom has two specific constants, namely atomic number and mass number. Atomic number is the number of protons or electrons present in an atom. It is the same for all the atoms of an element. Mass number of an atom is the sum of its protons and neutrons.

Many radioactive isotopes are used in medicine for imaging and treatment purposes. The specific isotopes used depends on the particular organ or body system being studied (for example, Xe-133 is used to image lung function and blood flow.) Technetium-99m is a common radioactive isotope using for a variety of medical applications. It is produced from the decay of Molybdenum-99 and has a half-life of 6.01 hours. What are some of the applications of Tc-99m? While harder to access, another radioactive isotope of technetium, Tc-93, has a half-life of 2.73 hours. If it were easier to harvest, would this be a good substitute for Tc-99m? (remember to explain why for full credit) While Tc-99m has a half-life of 6.01 hours, its decay product has a half-life of 213,000 years. While the medical community considers it to be reasonably safe, within the limits of testing, does this make sense considering both chemical and biological principles? What are possible ways that you might deal with or…

Iodine has 37 known isotopes. Therefore, the atomic mass has a range of 108-144 amu. Which of the following statements concerning iodine is correct? A) The isotopes of iodine have between 55 and 91 protons. B) An atom of iodine can have between 55 and 91 neutrons. C) The isotopes of iodine will always have the same number of neutrons, but the protons can vary. D) The isotopes of iodine have between 108 and 144 neutrons, but the number of protons will not vary.

A 10.00 mg sample of technetium-93 (92.91024898 u) is used to heat 125.4 g of water from 23.4 degree C to 87.4 degree C. How many minutes will be required to heat the water if all of the energy generated from the decay is used to heat the water?
